Hello- Need some advice on the best possible approach to make a servlet POST call from a servlet browser. Our Objective : From Appian user servlet browser, upload large files using graph API to sharepoint using chunking. This solution works perfectly fine on standalone eclipse but getting hiccups on Appian cloud. We cannot do this using traditional route as sharepoint API has a limitation of 250MB, our files are 1gb & beyond. couple of approaches i tried : Moved all the logic directly into the browser, including the session creation...but Azure rejected this approach not allowing to create session from the browser... 2nd approach Appian UI to HTML interface making a Servlet POST call to initiate a upload graph api session & return the token back to HTML & from here making all the grinding to sharepoint, here we are getting CSRF token rejection  Just want to know if there is a best working approach we could use. Any help here is really appreciated.

Hi, I'm not very knowledgeable about encryption algorithms, but I'm trying to figure out if I can send a text encrypted in AES (with the Encryption Functions plugin) so that it can be decrypted by a service external to Appian, using RSA.My guess is to use the RSA public key and store it in the Secure Credential Store of the plugin. This way, I encrypt in AES but with the RSA public key. Now, can the external service decrypt with its private key? thks

Hi when I generate a word document with an image example: {logo: CONS!APP_IMAGE} works perfectly, but when I have more than one image in the template. For example logo2 and I call the smart service as follows {logo: CONS!APP_IMAGE, logo2: CON!APP_IMAGE2} I get the following error: freemarker.core.NonSequenceOrCollectionException: The value you try to list is an extended_hash+string (fr.opensagres.xdocreport.document.images.ByteArrayImageProvider wrapped into f.e.b.StringModel), thus you must specify two loop variables after the "as"; one for the key, and another for the value, like <#... as k, v>). ---- FTL stack trace ("~" means nesting-related): - Failed at: #list logo as logo [in template "fr.opensagres.xdocreport.document.docx.DocxReport@7f2dbfc!word/document.xml" at line 4, column 6773] ---- Plugin: Advanced Document Templating      Version: 1.1.0      Smart Service: DOCX From Dynamic Template

Hello. In one of our projects, we need to download the files sent by clients through WhatsApp in order to perform a series of internal checks. We have reviewed some applications available in the marketplace and found the following: WhatsApp Business Connected System: Doesn't allow downloading files from WhatsApp. Symphony Connected System: In theory, it does support this functionality. However, we haven’t been able to test it yet, as it also requires a Symphony license. Has anyone here had experience using Symphony Connected System? Do you know of any other application that allows downloading files from WhatsApp, or any alternative approach you would recommend for this type of integration? Thank you very much in advance for your help. Best regards

Hi, I'm using the Google Charts Component a!googleTimelineChartField, and am wondering if there is a configuration I'm missing or a better solution to a timezone issue I've come across. I'm passing in queried data that is in the user's time zone (e.g., GMT+1:00), but the Timeline component seems to always convert it to UTC (tested with other time zones and they all seem to convert the shown chart data to UTC). The easiest solution is to apply local() on the data to essentially 'double apply' the time zone, so that when the timeline tries to convert it to UTC, it actually shows up in the user's time zone as required (e.g., a user's offset of -3:00 is double applied as -6:00 so that when the chart converts to UTC, adding 3 hours, it's shown to the user still as -3:00). With local() applied, it matches the data in the grid which does show the data in the user's time zone as usual: I'm wondering if I've missed some obvious conf

We are integrating Kafka plugin detected two incorrect behaviors:   The first (and most important) issue is a problem arising from the way we insert into the "tm_job_transaction" table. The "scheduled_date" field doesn't allow nulls, but the INSERT is returning a null in that field. After reviewing the database logs (RDS for MySQL), this is the SQL statement the plugin is generating.   As you can see, the description table is this. scheduled_date is not null But the plugin generate this SQL sentence   2025-10-09T08:12:39.717781Z1625671 QueryINSERT INTO tm_job_transaction (job_type_id, context_json, scheduled_date, status_id) VALUES (132, '{"topic":"sbna.payment_execution.ach_payment_exception_created.json.eb.01evts0039v1bed","partition":0,"offset":603,"key":null,"value":"{\\"PARTACCOUNTNUM\\":\\"031700013000500346\\",\\"detail-type\\":\\&

Hi, we have been using this plugin for a couple of months. Over the last few days, the smart service has been taking significantly longer — from a minimum of 3 minutes up to 1 hour. In the logs, we noticed the following message repeatedly. We have set both the connection timeout and the timeout to 10 seconds. Does this indicate that the mail server is not responding in time?

We have a need to updater pricing on our inventory items.  I was thinking about using a GridPlus grid over an Editable Grid for the increase in performance.  My question is, is there a way using a GridPlus grid to allow the user to increase the selected items by a certain percentage?  Example would be that they could select 20 different items, enter 3 in a filed for 3% and maybe click a button and all 20 items increase by 3%?  Any input or thoughts would be greatly appreciated.

I need to check if a function exists and then call it, using its name as a reference for both operations. I know that the functions doesruleexist and rulereferencebyname exist, but I don't know which plugin they belong to or if there is an alternative. PS: Due to business restrictions, I cannot use externalize() and internalize().
